Here is an example of a ketogenic diet:

  - 2 hard-boiled eggs for breakfast.
  - 1 cup of walnuts or almonds or pecans as a snack.
      - Eaten with a slice of sharp cheddar cheese (4g saturated fat).
      - Always rinse the nuts to make them more palatable.
      - This meal may be eaten twice a day.
  - 3 tablespoons of chia seeds soaked in water, as a snack.
      - Like a high fat/protein version of oatmeal.
  - Peanuts and macadamia nuts as needed for hunger.
  - Steamed vegetables (broccoli, kale, spinach, brussels, zuchini, tomatoes).
      - Eaten with 8 tablespoons of olive oil.
      - A very large serving of steamed vegetables.
      - Salt/seasoning however you prefer.
      - This is dinner.

Once a week, eat a cheeseburger. Or twice a week: rotisserie chicken and olive oil, or coleslaw and guacamole and chicken.

This high-fat, low carb diet can be maintained with no difficulty for decades. Also, it is an ideal diet for insulin-dependent diabetics.

It's cheap, healthy, and you won't be hungry.
